Forests: Changes in the Land

Introduction

The image to the right shows acres of forest in Mexico being cut down and burned to make way for agricultural land.

Approximately 50% of a tree's weight is comprised of carbon that originated from atmospheric carbon dioxide. What happens to this carbon when forests are cut down to make way for agriculture and cattle farming, or simply to feed a family.

In Part A, you will use videos and an interactive to explore the impact of deforestation in the Amazon. You will then investigate a mini-case study on using Inga trees to mitigate environmental problems caused by slash and burning farming methods.

In Part B, you will use the Global Forest Cover Tool at World Resources Institute to research changes in forest cover based on an original research question developed by you.

After completing this investigation, you will be able to:

Keeping Track of What You Learn

Throughout these labs, you will find three kinds of questions. Your teacher will let you know which answers you should record and turn in.
